So, this is the Matrix and Inception at the same time, not at all confusing. Jesus, the only reason i keep reading is because i expect a good ending, but it just keeps going with so many twists this story will become a prion and give me a disease.
At this point not even yukiko is enough reason to invest into this.
She just gets one page cameos and is a side romantic interest at best. While Ai has neither the personality nor the body to be a replacement. Especially when she's constantly acting like a damsel in distress + Morpheus + Agent Smith all in one package.
